Two of Ireland's biggest sporting names have had it out on Twitter after the age old question of "who would win?" was asked.
Former WWE Champion Sheamus and the UFC Featherweight, Conor McGregor wasted little time in going at on the social media site - after Sports Illustrated Now asked followers who would win.
Two worlds colliding
It was Sheamus who would fire the first shots, telling followers exactly what he thought of the challenge being pushed on him.
McGregor naturally wasted little time in responding, and his retort opened a can of worms which all then got rather heated and personal.
And then again Sheamus...
And McGregor again...
And once more Sheamus...
The two soon after ended the argument, discussing in the end about getting together for a whiskey and in Sheamus' own words a #TradtionalIrishChristimas that consists of fighting everyone in sight.
It's bizarre how quickly this blew up and resolved itself but it does still leave fans with the question - who would win in a fight between WWE's Sheamus and UFC's Conor McGregor?
